DOOR-LOCK.

Specification of Letters Patent.

Patented Dec.4l:,191'7.

Application filed June 10, 1914. Serial No. 844,339.

To all whom it may concern:

Be it known that we, CLIFFORD TKAUT, a citizen of the United States, anda resident of Newportfln thefcounty of Campbell and State of Kentucky,and VVILLIAM B. Conn- MAN, a citizen of the United States, and aresident of Covington, in the county of Kenton and State of Kentucky,have invented certain new and useful Improvements in Door-Locks, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification.

In the construction of doors for cells .in asylums for the insane andsuch like, it is required to have a door which is safe against springingopen when locked. Such doors, although of open metallic framework, mustbe stiff and strong, and even then a pressure on the top edge of thedoor is liable to cause enough springing of the metal parts of the doorto seriously damage the door or even to allow the locking bolt to slipout of its socket. F or this reason, it is found necessary to providejump bars which when op erated serve to secure the whole side of thedoor to a series of studs in the door j amb.

In the door to be hereinafter specifically pointed out, and its noveltyclaimed, all of the above requirements are provided for, and in additionthere is provision whereby the door cannot be locked without firstshifting the jump bar into holding position, and the jump bar cannot bemoved out of such position without first unlocking the door.

In the drawings,

Figure l is a front elevation of the door closed and taken from theoutside, partly in section.

Fig. 2 is a horizontal section through the door looking toward the stopstud on the jump bar.

Fig. 3 is the jump bar, in perspective.

Fig. 4 is the angle plate on which the jump bar is mounted, also inperspective.

Fig. 5 is a vertical sectional view of the door closed against the angleplate on the jamb of the door, partly in elevation, and with the sectiontaken outside of the line of the jump bar studs.

Figs. 6 and 7 are details in perspective of the corner portions in theside and bottom channel bars respectively of the framework of the door.

The framework of the door is composed of four channel bars 1, 1, for topand bottom,

and 2,- 2, for the sides of the door, with suitable lattice work for thebody of the door. To strengthen the door, we provide for a strongand'durable means of connectbent up for the bottom, and down for the topbar, at 3. The base of the side bars is cut away at 4, so as to allowthe flanges 55, .5, to abut against the ends of the flanges of theadjacent channel bar, and the tongues are then riveted at 6 to the baseof the adj acent bars of the inside of the channels thereof.

Fitted into the open side of the channel bars and preferably bolted inplace are the finishing plates 7. Angle plates 8 are set into thejamlos, and at the hinged side of the door the hinges 9, 9, are securedto the plates 8 and to the plates 7, some of the bolts 10 for securingthe finishing plates serving also to hold the outer hinge leaf.

Mounted on the channel bar and its finishing plate at the front edge ofthe door is an L-bar or angle plate 11, the length of the door. Alongthe flange of this angle plate are a series of slots 12 for slidablymounting thereon the jump bar 13. Rivets 14 are used, preferably, forthis purpose (Fig. 5), which pass through the holes 15 in the jump barsand the slots 12 above mentioned and slide in the slots.

It will be understood that this jump bar is mounted onthe outside of theangle plate. In this jump bar are slots 16, having large eyes 17 at thelower end; and it located so as to register with the eyes 17, when thejump bar is in raised position, are apertures 18 in the angle plates.Studs 19 having enlarged heads 20, are mounted in the door jambs,preferably so as to be held by the plates 8 thereon, and extend outwardly so as to pass through the apertures 18 and the eyes 17 of theslots in the jump bar. When the door is closed and the jump bar is inraised position on the angle plate, the heads of the studs willnaturally pass through the plate and bar. A handle 21 on the jump barmay then be used to push it down on its slidable mounting so that theslots 16 will engage the shank of the studs and hold the heads 20thereof in locked position. Thejump bar will thus hold the door fastclosed at all places where it is desired to locate studs so as toprevent the bending of the door at any point to spring out or damage thelocking bolt. It will be understood, of course, that the studs and slotscan be arranged so that instead of pulling down the jump bar to lock itthe movement can be in the opposite direction.

The lock is mounted in a casing 22 riveted preferably to a framecomprising a cross bar 23 secured to the two upright channel bars 2, andan angle 24esecured to the cross bar and the upright channel bar. Thereis only the bolt 25 of this look shown, as any desired construction ,oflocks can be employed. The bolt 25 passes through the channel bar 2, thefinishing plate 7 and the angle plate 11. Located in the jump bar, andextending through a long slot 26 in the flange portion of the angleplate is a block 27 This block is positioned so that when the jump baris in raised position permitting the heads 20 of the studs 19 on thejamb to pass through the eyes 17 on the bar, then the block 27 willextend directly across the path of the bolt 25. When the jump bar ispushed down, however, to lock the heads 20 to the door, then the blockis out of the way of the bolt which may be shot into place for locking.Once the bolt is shot, however, it

stands in the path of the jump bar block,v

making it impossible to raise the bar so as to release the heads 20.

We not only, therefore, provide an exceptionally stout frame for thedoor, and aump bar of simple constructlon and easyoperation, inconnection with such frame, but We also make the door foolproof, al-

ways requiring a complete locking of the door and preventing a releaseof the ump tending beyond the front edge thereof,

headed studs on the frame, apertures in the angle plate to receive saidstuds, and a bar slidably mounted on the angle plate and having slotswith wide portions to receive the heads of the bolts, and narrow Iportions to engage under the heads, a locking bolt extending behind theangle plate,

a lug on the bar to be engaged by the bolt,

and a slotted aperture in the angle plate for the lug.
